Plastic Scratches
SprintDrives plastic scratches are made of flexible and durable nylon. Since there is no contact between steel and steel, the chain has a very smooth run. The plastic scratches are energy-saving, noise-reducing and cost-saving. Various plastic materials are available: nylon, fiberglass-reinforced nylon, Zytel, and FDA grade.

The advantages of plastic scratches:
Noise-insulating
flexible / flexible
Low frictional resistance and energy-saving
More cost-effective due to longer service life, as less wear on the chain and trough floor
make wear bars superfluous
Easy and very quick to install or replace
